Brush for receptacles



July 4, 1950 M. T. GLASS BRUSH FOR RECEPTACLES Filed June 13, 1947 In ventor Martin 7'. Glass A. MW EM Patented July 4, 1950 UNITED STATES PTENT QFFECE 1 Claim.

This invention relates to new and useful improvements in brushes and the primary object of the present invention is to provide a brush particularly useful for cleaning coliee pots and other cylindrical receptacles.

Another important object of the present invention is to provide a brush so designed as to permit the same to be extended into a receptacle under tension to bear against the inner wall of the receptacle, thereby cleaning the area thoroughly upon a back and forth or up and down motion of the brush relative to the receptacle.

A further object of the present invention is to provide a brush that is quickly and readily bent or twisted into the shape desired.

A still further aim of the present invention is to provide a brush that is simple and practical in construction, strong and reliable in use, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a, perspective view of the present invention; and,

Figure 2 is an enlarged sectional View taken on line 2-2 of Figure 1.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral lil represents the body of the present cleaning brush generally, comprising a core l2 extending centrally through a substantially cylindrical body of bristles Id.

The core is preferably formed of a pair of twisted wires, however any other suitable means may be employed without changing the functions for which the brush is intended.

One terminal portion of the core, as for example i6, projects outwardly from the adjacent terminal portion of body M and is suitably secured to a handle it, and the other terminal portion of the core terminates intermediate the adjacent terminal portion of the body [4.

In practical use of the device, the body of the brush is spirally bent or Wound by hand or ma chine with the terminal loops 20 at each end of the body of reduced diameter than the central loop portion of the body.

The axis of the handle I8 is in alinement with the axis of the body I to permit an equalized coil action of the body by the handle.

The body is inserted into a receptacle, such as a coffee pot, and b pressing inwardly on the handle it, the body is compressed slightly so that the outer extremities of the body bear against the inner periphery of the receptacle. When pressure is released from the handle, the body again retains its normal shape and may be easily withdrawn from the receptacle.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new is:

Cleaning brush including a spiral body having convolutions spaced from each other to permit the same to be threaded into the mouth of a recep tacle, said body comprising a central reinforcing and resilient member extending continuously within each of the convolutions of the brush, and bristles carried by the convolutions of said body and projecting radially therefrom, said body including central convolutions and end convolutions, said end convolutions being of a reduced diameter than said central convolutions.
